Abstract | To provide a lens driving device and adjustment method of the driving device that make an inclination (angle of inclination) between an optical axis of a lens provided in a voice coil motor and an image sensor stand 0 degree by a simple method.SOLUTION: A lens driving device adjustment method is configured to: provide a lens 20 in a voice coil motor 10, make an optical axis 21 of the lens incline toward one side of a normal line 111 of a bottom surface 31 of the voice coil motor 10, form an inclination angle θ2, and form at least three supporting pins 30 in a bottom surface 31 of the voice coil motor 10; perform processing to these supporting pins 30 on the basis of an inclination direction of the optical axis 21 and an angle of the inclination angle θ2; thereby locate the entire bottom surface of the supporting pin 30 on a first reference surface RS1, and make the optical axis 21 perpendicular to the first reference surface; and couple an engaging surface 51 of the image sensor 50 to the bottom of the supporting pin 30, and locate the engaging surface on the first reference surface RS1. According to this adjustment, the optical axis 21 becomes perpendicular to the engaging surface 51 of the image sensor 50.SELECTED DRAWING: Figure 8
【課題】ボイスコイルモータに装設されたレンズの光軸とイメージセンサーとの傾き(傾角)を簡易な方法で0゜とするレンズ駆動装置及びその調節方法を提供する。【解決手段】レンズ20がボイスコイルモータ10に装設され、その光軸21がボイスコイルモータ10の底面31の法線111の一側に向けて傾斜すると共に傾角θ2が形成されると共に、少なくとも3本の支持ピン30がボイスコイルモータ10の底面31に形成され、光軸21の傾斜方向及び傾角θ2の角度に基づいてこれら支持ピン30に対する加工が行われることにより、支持ピン30の底面は全て第一基準面RS1上に位置され、光軸21を第一基準面に対して垂直とし、イメージセンサー50の組み合わせ面51が支持ピン30の底面に結合されると共に第一基準面RS1上に位置される。この調節により、光軸21がイメージセンサー50の組み合わせ面51に対して垂直になる。【選択図】図8 |
